` PIrE CLAMP Application filed April 22,

This invention relates to pipe repairing devices, more particularly to pipe clamps.

One of the objects of the invention is to provide a new and improved pipe clamp which can be manufactured at a very low cost.

. Another object of the invention is to provide a pipe rclamp which is more easily applied to and removed from a pipe than has obtained in pipe clamps as hitherto constructed. i

Other objects of theinvention will be in part obvious and in part pointed out hereinafter. Y

'Ihe invention accordingly consists inthe features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, wherein I have illustrated a preferred form of embodiment of my invention,

f '25 Figure 1 is a view in perspective of one n of the clamping members of my improved pipe clamp,

Figure 2 is aV cross sectional view taken on the line2-2 of Figure 4,

Figure 3 is a longitudinal sectional view taken on the line 3 8 of Figure 2, and

Figure 4 is an elevational view show-` ing the device positioned upon a pipe.

Referring now to the drawings, wherein similar reference characters refer to similar 4.5 prises a neck 5 and the hook member 4 andV each hook member is separated from its neighbor by a space 6.

'Ihe opposite edge of the clamp member 1 is flattened out as clearly shown in Figures i150 l and 2 said flattened portion, indicated at 1930.` serial iro. 446,236;

7,' beingprovided with a plurality of apertures 8.. l

|lhe clamp it will be noted is formed .of

twoy similar partsk l and 9, the construction vof the clamp member 9 corresponding in all 55 respects with the clampmember 1.

It will be noted that' the engaging edge lO'ofeachof the hookmelmbers 8 lies in a directionparallel with the longitudinal axis ,of the Vclamp and that the space within each y of the hook members is defined by rectangularly `disposed edges. Y p

In assembling the clamp two of the clampking` members such asiland 9 are held in reversed positions relatively to each other QJ .and the necks lof each of, the clamp mem.- bers are passed .through the propery space `6 separating the respective hookk members. When this has been accomplished the clamp members are moved `in a longitudinal .dik rection relatively to eachother. When ,this has y been 1 accomplished the clamp members such. as land 9 ,arepositionedupon a pipe indicated .at l1, as shown in Fi ure 2. v l Assuming that an aperture suc as shown 75 at 12in Figure 2 is to be closed, a rubber gasket 13 isipreferably positionedl over the openingto be closed as shown in Figure 2. The clamp members l and 9 are `then se- `curelyclamped'about the pipe 1l and the 80 y'gasket'l as by means of the clamp bolts 14 which are extended through the registering apertures 8 ofthe respective clamp members. f i Thus itr willv be. seen that the clamp may `be' assembled by a simple operation such Vas-v lis above described; To remove ythe clamp from the pipe it is merely necessary to ren move the nuts of the clamp boltsi wheref upon the clampmembers will lfall aparty. 90

" It will be'notedthat the `clamp lmembers 1 and9 are identically constructed and that Y both lmay be cut from sl1eet'-metal by the samedie.V y p, I n' As many changes L could be` made in the {above' construction and many apparently widely different embodimentsr of this invention` ,could be made without departing fromthescope thereof,'it is intended that all matter contained in the above description oraal shown in the accompanying drawings 'shall be interpreted as illustrative only and not 1n a limiting sense.

It is also to be understood thatthe language used in the following claims is intended to cover all ofthe generic and specific :teatures ot the invention herein described, and allA statements of the scope of the invention, which, as a matter of language mig-ht -be said to :tall therebetween.. e Having thus described my invention, what I claim as new and desire to secure byv Liet!` ters Patent is 1. VA Clamp comprising :a pair of'mutually engaged members having rounded portions adapted to -it about a portion of a pipe, said members having their edges ,provided with op ositely extending, longitudinally interlo'c-ing projections, and means?. passing through theopposite edges Vo said 'members for securing them to a pipe.

, Y 2. A pipe clamp comprising. a pair of clampv members,feach"'being provided with a rounded portion adapted to tit -a'boutra por- "tion of a pipe, each ymember `having one ol" its lateral edges provided with va `plurality of longitudinally extending, "hook Jshaped projections adapted for mut-ual engagement with the similarly disposed lro'olz shaped members 'of the other clamp menber, 'the op- ,posite edges 'of said 'clanrp :members `-being `apertured, and means adapted to pass through said :apertures for holding 'said i clamp members inpositi'on upon a. pipe.'

' Ethrough said apertures whereby tightly` to T3. A clamp vcomprising a'pairofsirnilarly formed clamp members, each ol'wliich is ,provided with a rounded portion Yadapted to 5. As a new article of manufacture, a pipe clamp member having a rounded portion, one of the lateral edges of said member being provided with a plurality 'ol' longitudinally extending hook shaped members, and its opposite edge provided'with a plurality of apertures.
